Qualification of match results

ABSTRACT

Qualification of data matches can be improved relative to existing approaches by use of first, second, and third similarity criteria, which can be used to identify a set of near match record pairs, identify a set of actual match record pairs and to flag as near matches those record pairs of the set of near matches that were identified as actual matches, and to identify and flag one or more suspect matches.

TECHNICAL FIELD

The subject matter described herein relates to qualifying of match results, for example for records in one or more databases.

BACKGROUND

Database management processes can include one or more aspects that require identification of matching records. As an example, a de-duplication process can include determining whether two or more records are at least partially duplicative. Records determined to refer to a same entity (e.g. a same person, a same instance of a business process, a same invoice, etc.) can be combined if none of the duplicate records include all information that should be retained in a single record representation of the entity. Alternatively, if combining of the records is not necessary, for example because at least one of the records includes all information that should be retained in a single record representation of the entity, one or more of the matching records can be deleted. De-duplication can be useful when partially overlapping data sets are merged or otherwise combined.

SUMMARY

Consistent with one or more aspects of the current subject matter, a set of near match record pairs can be identified by applying first similarity criteria to a set of record pairs. A set of actual match record pairs can be identified, and those record pairs of the set of near matches that were not identified as actual matches can be flagged as near matches by applying second similarity criteria to the set of near match record pairs. One or more suspect matches can be identified and flagged by applying third similarity criteria to the set of actual match record pairs.

DETAILED DESCRIPTION

In general, qualification of match results can include identification of two types of match results: near matches and suspect matches. Using previously available approaches, a user might query a set of suspect matches that are identified as suspect due to a low match similarity. However, this approach can fail to account for matches that are deemed to be suspect due to special data nuances. Additionally, the requirement to manually sort the data and observe the match groups to look for matching records that contain the questionable nuances can be a significant disadvantage.

As used herein, a near match includes two or more records that do not meet one or more minimum similarity threshold criteria requirements in order to be determined to be duplicates, but that nonetheless “close” to being duplicates. Records can be close non-matches as the result of a direct similarity comparison being very close to the minimum similarity threshold, or as the result of special data nuances that are common to certain data elements.

Several examples of near matches are described here for illustration purposes only. In a first example, a minimum threshold of similarity required for a person's first name can be 80%. When comparing the names “John Smith” and “Johm Smith” these records are determined to be non-matches because the first names are 75% similar, less than the minimum. However, assuming that a minimum similarity threshold for a near match first name is 74%, these names would be considered to be near matches. In this case, a direct string comparison algorithm can be used to flag “John” and “Johm” as near matches.

In another example, a minimum threshold of similarity for phone numbers can be 100%, after excluding noise data such as spaces and delimiters. According to this criterion, phone numbers such as 866-325-8165 and 866-325-8156 are determined to be non-matches. However, these phone numbers can be considered to be near matches because the only difference is that two of the numbers are transposed. The algorithm used in this example to flag near matches can include a special adjustment option for transposed characters.

In another example, a minimum threshold of similarity for email addresses can be 100%. According to this criterion, emails such as tom.schmidt@domain.com and tschmidt@domain.com are determined to be non-matches. However, these emails can be considered to be near matches because they have the same domain name, and the user names may be acceptable variations of each other. The algorithm used in this example to flag near matches can include a special adjustment option for abbreviated strings.

In another example, a minimum threshold of similarity for firms to match can be a 100% match, including any numeric portion (e.g. a branch or plant number). According to this criterion, firms such as First National Bank Branch 200 and First National Bank Branch 600 are determined to be non-matches. However, the firms can be considered to be near matches because they have the same firm name with the only difference being the numeric component. The algorithm used in this example is to flag near matches can include a special adjustment option for numeric words.

In another example, a minimum threshold of similarity for Japanese last names can include the requirement that they be written in the same writing script. According to this criterion, when last names are written in a transliterated script for the purpose of indicating how to pronounce the name, the last name transliterated to Latin script would therefore not match the same last name transliterated to Japanese hiragana script, and the two entries would be identified as a non-match. However, these transliterated last names can be considered to be near matches because they are versions of the same last name but in different scripts. The algorithm used in this example to flag near matches can include a special adjustment option for inter-script matching.

FIG. 1A shows a table 100 illustrating an example of a pair or near matches. Although the two records do not match based on the criteria defined in the match rules, it may be a advisable for these records to be manually review because the names are very similar and the only difference in the phone numbers is a transposition of two digits.

Suspect matches are records that meet the minimum similarity threshold criteria requirements and are therefore determined to be duplicates. However, the comparison process may encounter some feature about the match that makes it suspect. Match groups can be suspect as the result of barely meeting the minimum similarity threshold, or as the result of special data nuances that are acceptable as a probable match but should probably be manually reviewed (e.g. by a user) before determining them to be true duplicates. While near matches are non-matches that are very close to being matches, suspect matches are matches that are very close to being non-matches.

Several examples of suspect matches are described here for illustration purposes only. In one example, a record containing a first name can be identified as matching with a record containing only a matching initial, for example such that “John Smith” and “J. Smith” can be identified as potential matches. Records that are identified to match based on this type of criteria can be flagged as suspect matches. The algorithm used in this example to flag suspect matches can include a special adjustment option to use first name initialism for matching purposes, which can be disabled for flagging of matches as suspect.

In another example, a record containing a name with a postname (e.g. Jr., Sr., III, etc.) can be identified as matching with a record containing the same name without a postname. For example, a record containing “John Smith Sr.” can be identified as a potential match with “John Smith.” The algorithm used in this example to flag suspect matches can include an option for blank matching for matching purposes, which can be disabled for flagging of matches as suspect.

In another example, a record containing a street address with a street type can be identified as matching a same address with a different street type. For example, a record containing “100 Main St” can be identified as a potential match with “100 Main Ave” optionally if some other data component such as person name or firm name also matches between the records. The algorithm used in this example to flag suspect matches can include disregarding the street type for matching purposes, but considering it for flagging.

In another example, a record containing an address with a single unit can be identified as matching a same address with a compound unit. For example, a record containing “100 Main St Apt 300” can be identified as a potential match with “100 Main St Apt 300-C” again optionally if some other data component such as person name or firm name also matches between the records. The algorithm used in this example to flag suspect matches can include a special adjustment option for partial strings for matching purposes, which can be disabled for flagging of matches as suspect.

FIG. 1B shows a table 150 illustrating examples of suspect match groups. Groups 6 and 9 contain suspect criteria because they match due to name variations, and groups 7 and 8 contain suspect criteria because the first name in one record matches the middle name of the other record. Before automatically assuming that they are duplicates, it may be desirable for these records to be manually reviewed.

Previously available approaches to analyzing matched records, for example for identifying records incorrectly designated as matching when a non-match should have been indicated or records incorrectly designated as non-matching records that should match, have generally required review of a large number (typically thousands or even millions) of records and sorting in various ways to identify patterns of unexpected results. Using such approaches, after a pattern of unexpected results is identified and one or more adjustments to the match-finding algorithm are made, the analysis is repeated and reviewed again. Such approaches have generally lacked a satisfactory way to reduce the number of records to analyze or to quantify or otherwise readily visualize differences between results of an initial analysis and one or more of the repeated analyses. It is not uncommon for this fine-tuning process to take months.

To address the above-noted and potentially other deficiencies associated with previously available approaches, implementations of the current subject matter can permit filtering of records so that only those records requiring manual review or other human action are displayed in isolation. In this manner, patterns of unexpected results can be identified very quickly, thereby resulting in improvements in one or more of accuracy of results (e.g., seeing only records close to the threshold can make undesired results more readily apparent), business efficiency (e.g., a several-month fine tuning project can be reduced to days), and user experience (e.g., with an application using advanced intelligence, a user can more readily obtain desired results without requiring knowledge of match technology).

Instead of treating all non-matching records the same and all matching records the same, approaches consistent with the current subject matter can include flagging as near matches those non-matching records that are close to being matches and as suspect matches those matching records that are close to being non-matches. For example, in some implementations, match policies can be configured to include two stages of analysis based on first and second criteria. The first similarity criteria can be used to identify near matches, and can include more lenient similarity criteria (than the second similarity criteria) for specific data components. The second similarity criteria can be used to identify real or actual matches (referred to herein as “actual matches”), and can optionally include one or more existing approaches useful for determining matching criteria. A larger number of potential matches, or at most a same number of potential matches, will generally be identified based on the first similarity criteria than the second similarity criteria because of the increased leniency of the first similarity criteria relative to the second similarity criteria. In one example, the first similarity criteria can be applied in an initial screening process, and any identified potential near matches can then be processed using the second similarity criteria to identify actual matches. Record pairs are flagged as near matches when they match at the near-match level but do not match at the actual match level.

When records match at the actual match level, a group of matching records can be further compared using third similarity criteria, which are stricter (e.g. less lenient) than the second similarity criteria. A group of matching records can be flagged as suspect when the records match at the actual match level (e.g. based on the second similarity criteria) but do not match with the third similarity criteria. When a group of matching records contains at least one record pair that meets this condition, the whole group of matching records can be flagged as a suspect match group.

An analytical approach consistent with that described above can result in a matching solution that identifies groups of matching records with best practice configurations. In addition, some non-matching records (e.g. those records meeting the first criteria but not the second criteria) can be further flagged as being close to being matches, and some suspect records (e.g. those records meeting the second criteria but not the third criteria) can be further flagged as being close to being non-matches.

A user can control the similarity differences and exactly what special allowances of data nuances are allowed for the determination of both near matches and suspect matches. For example, one user may want the match pair “John Smith” and “J. Smith” to be flagged as a suspect group, and another user may not. Therefore, the rules can be configurable.

Qualification of match results can advantageously be used in improving accuracy of match results, for example by assisting a user in determining whether the matching criteria require adjustment or other tuning. No set of best practice configurations is likely to be optimal for all data sources in all organizations. It is generally likely that, for a particular project, the matching criteria would need to be either tightened or loosened to accomplish the best possible matching results.

Reviewing identified near matches can assist in identifying whether the matching criteria needs to be loosened. When a review of near matches reveals that they truly should not have been identified as actual match, then the matching criteria do not require loosening. However, when a review reveals that many of the near matches really should match, then the matching criteria should advantageously be loosened.

In a similar but converse manner, reviewing identifies suspect matches can assist in determining whether the criteria for identifying actual matches (e.g. the second criteria) needs to be tightened. When a review of the suspect matches reveals that they truly should match, then the matching criteria does not have to be tightened. But when a review reveals that many of the suspect matches really should not match, then the matching criteria should advantageously be tightened.

Previously available approaches generally lacked a desirable approach to querying for near matches. Typically, the whole data set (sometimes numbering millions of records) would be sorted in various ways and the data manually inspected to search for record pairs that were non-matches but close to being matches. Using implementations of the current subject matter, record pairs are specifically flagged as near matches such that a data consistency application (such as, for example, Data Cleansing Advisor available from SAP AG of Walldorf, Germany) can filter on those records and display them together for a user to see them in isolation. When a user sees the near matches in isolation, it becomes apparent whether or not the matching criteria should be loosened.

Similarly, previously available approaches could generally users to query suspect matches that were suspect due to a low match similarity, while generally lacking a desirable approach to querying for suspect matches those that were suspect due to special data nuances. Again, the user would generally be required to sort the data and observe the record pair looking for matching records that contain the questionable nuances. Using implementations of the current subject matter, record pairs are specifically flagged as suspect matches such that a data consistency application can filter on those records and display them together for the user to see them in isolation. An observation of these suspect matches can make it readily apparent whether or not the matching criteria should be tightened.

By analyzing the near matches and suspect matches in isolation, a user wishing to perform fine-tuning of the matching criteria can optionally do so using a user interface including one or more screen views that allow adjustments to any one or more of the first, second, and third criteria to be made directly. FIG. 2 shows a screenshot 200 illustrating features of a user interface consistent with this implementation of the current subject matter. As shown in FIG. 2, a slider control 202 is an example of a user interface element that can be used to receive user input for altering a similarity requirement for a data component (in the example, person data such a name) and special data nuances 204 for matching person name data. The illustrated example is for second similarity criteria (e.g. for determining an actual match). Similar approaches can be used to allow a user to modify first similarity criteria and third similarity criteria as well. Additionally, a similar approach can be used for receiving user input for matching other data components, such as for example organization name, address, phone number, etc.

In other variations, a user interface can include an auto-generated suggestion feature that proposes changes to one or more of the first, second, and third criteria. The user interface can also include the ability to illustrate the impact that any change would make to the data. The result is that the number of near matches or the number of suspect matches can be reduced as desired by the user. Using previously available approaches, making a change to the match rules would generally be performed without ready access to statistics or other metrics indicating how the change to the match rules impacts the results. Use of near matches and suspect matches counts produced using implementations of the current subject matter can allow a data consistency application to generate and display statistics or other metrics indicative of impact of a single change, which can advantageously provide a user with information needed to make an informed decision on whether the change was the right thing to do. The fine-tuning process thereby can become much more precise and accurate.

Qualification of match results can also be advantageous for improving business efficiencies. Using previously available approached, all non-matching records were typically treated equally, and all groups of matching records were treated equally. In contrast, using a data consistency application having the abilities described herein to automatically flag and filter non-matching records that are close to being matches and matching records that are suspect, users can make decisions on fine-tuning the matching criteria with just a few clicks and a very little time in observation of these two types of records.

Another efficiency benefit that can result from the flagging of suspect matches is that the high-confidence match groups (those not flagged as suspect) do not need any manual intervention. Accordingly, such match groups can generally be routed automatically to have post-match processes applied. Such post match processes can include, but are not limited to consolidation of data, formation of a best record, disregarding duplicate records, or the like. The low-confidence match groups (e.g. those flagged as suspect) can be routed to a review process in which they are reviewed manually, for example so that a user can research any necessary issues, etc. before determining whether the records match or not.

FIG. 3 shows a process flow chart 300 illustrating features of a method consistent with implementations of the current subject matter. At 302, first similarity criteria are applied to record pairs that include first record and second records. The applying of the first similarity criteria a given record pair includes comparing a first value in a field of the first record with a second value in a corresponding field of the second record to determine whether the record pair qualifies as a near match. At 304, second similarity criteria are applied to record pairs identified as near matches to determine whether the record pair qualifies as an actual match. Near matches not qualifying as actual matches can be flagged as near matches. Actual matches are further reviewed at 306 by applying third similarity criteria to record pairs identified as actual matches to flag actual matches that should be classified as suspect matches. At 310, the flagged near matches and/or suspect matches are provided for further analysis, which can include displaying the near matches and/or suspect matches to a user via a user interface, printout, or other display approach. Alternatively or in addition, the actual matches (e.g. those not flagged as either of near or suspect matches) can be routed automatically to have post-match processes applied.

In an implementation of the current subject matter illustrated in the architecture diagram 400 shown in FIG. 4, a computing system 402 can perform operations consistent with one or more features of a database management system, enterprise resource planning system, or the like. A match qualification module 404 can be implemented in the computing system 402 or in another computing system that can access one or more data repositories 410 that store data. The one or more data repositories 410 can be stored on computer readable storage media that are a part of the computing system 402, or alternatively or in addition, on one or more computer readable storage media that can be accessed by the computing system 402 over one or more data connections, which can include a data bus, a local network connection, a wide area connection, or some other connection accessible via a network 412.

The computing system 402 can optionally include one or more physical programmable processors.

Client machines 420 can access the computing system 402, either via a direct connection, a local terminal, or over a network 412 (e.g. a local area network, a wide area network, a wireless network, the Internet, or the like).

 15. A computer-implemented method as in claim 14, further comprising routing the set of actual matches for automatic application of one or more post match processes.
 16. A computer-implemented method as in claim 15, wherein the one or more post match processes comprise at least one of consolidation of data, formation of a best record, and disregarding one or more duplicate records.
 17. A computer-implemented method as in claim 14, wherein the providing comprises presenting a user interface displaying at least some of the flagged near matches and/or the flagged suspect matches and supporting functionality that allows a user to perform fine-tuning of one or more of the first criteria, the second criteria, and the third criteria.
 18. A computer-implemented method as in claim 17, wherein the user interface further comprises an auto-generated suggestion feature that proposes changes to one or more of the first criteria, the second criteria, and the third criteria.
 19. A computer-implemented method as in claim 17, wherein the user interface further comprises functionality for illustrating an impact of a change to one or more of the first criteria, the second criteria, and the third criteria on classification of the record pairs.
 20. A computer-implemented method as in claim 14, wherein the providing and the applying of the first criteria, the second criteria, and the third criteria are performed by at least one system comprising at least one programmable processor.
